Deconfinement of nonstrange hadronic matter with nucleons and Δ baryons to quark matter in neutron stars

Abstract: We explore the possibility of formation of ∆ baryons (1232 MeV) in neutron star matter in an effective chiral model within the relativistic mean-field framework. With variation in delta-meson couplings, consistent with the constraints imposed on them, the resulting equation of state is obtained and the neutron star properties are calculated for static and spherical configuration. Within the framework of our model the critical densities of formation of ∆s and the properties of neutron stars are found to be very… Show more

“…It is to be noted that this set of delta couplings has been used in a previous analysis for formation of ∆s and the resultant NS properties. 49 For this set the delta potential obtained in SNM is -110 MeV, which is quite larger than the range suggested for the same by. 39 The obtained value of potential is, however, consistent with the range prescribed by.…”

“…The ∆s are formed in NSM as resonance states via the strong interactions. 49 The formation of these baryons are controlled by the charge neutrality and chemical potential conditions in order to obtain a stable charge neutral NS configuration at chemical equilibrium. We then take these baryons at equal footing with the nucleons.…”
